VENTILATING ATTACHMENT FOR HEATERS.

SPECIFICATION forming part of Letters Patent No. 548,079, dated October 15, 1895.

Application filed February 6, 1895- Serial No. 537,498. (No model.)

To aZZ whom it may concern:

Be it known that I, WILLIAM MILLER, of New York city, in the county and State of New York, have invented a new and Improved Ventilating Attachment for Heaters, of which the following is a full, clear, and exact description.

This invention relates to certain improvements in ventilating attachments for heaters, and has for its object to provide a device of this character of a novel and inexpensive construction bymeans of which a portion or all of the apartments of a building may be conveniently and thoroughly ventilated.

The invention consists in a series of branch pipes leading from the rooms or apartments to be ventilated, a heater, an air flue or pipe connected to and supplied with air from said branch pipes, a valved connection between the fire-pot of the heater and said air-flue, a smoke pipe or flue having valved connections with both the heater and the air-flue, and means for controlling said valved connections in such a way that the vitiated air is drawn from the apartments or rooms to be ventilated in substantially a uniform manner.

The invention also contemplates certain novel features of the construction, combination, and arrangement of the several parts of the improved ventilating apparatus whereby certain important advantages are attained and the device is made simpler, more easily operated, and otherwise better adapted for use than other similar devices heretofore employed, all as will be hereinafter fully set forth.

The novel features of the invention will be carefully defined in the claims. I

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side view of a heater, which may be of any preferred form, provided with my improvements, the attachment constituting my invention being shown in vertical axial sections. Fig.2 is a fragmentary view showing the attachment in vertical axial section, the parts being represented in positions diiferent from the positions seen in Fig. 1; and Fig. 3 is an enlarged detail view showing theconstruction of the smoke-pipe damper or valve controlling the connection between the,

smoke-flue and the smoke pipe or outlet of the heater. Fig. 4: is a fragmentary sectional view showing a modified arrangement of the de* vice wherein the vitiated air withdrawn from the apartments to be ventilated is admitted to' the hot-air space of the heater to be heated and returned-to the room.

. In the views, A represents the heater, which may be of any variety, and may be a hot-air or steam heater, and 16 represents the airsupply pipeleading into the fire-pot of the same below the grate, said air-supplypipe connectingat its outer end with a valve-box 17, from which extends upward a second airpipe 15, the upper end of which communicates with the base portion of a drum 12, herein shown as attached to the side of the heater A.

The drum 12 is in communication with the main air pipe or flue 13, which is connected to a series of branch pipes 14 of any number, these branch pipes leading from the various rooms or apartments to be ventilated and having their mouths communicating with said apartments by preference near the floor and covered over in any way-as, for example, by means of gratings; The drum 12 is arranged to surround the said pipe or outlet 10 of the heater A, this pipe 10 being in communication withthesmoke-fiue 11, leading to the chimney, and having its outer end open, as clearly seen'in the drawings, and adapted for communication with the drum 12, being provided with a valve 22, pivoted at one side of said open end and adapted, when lowered to the position seen in Fig. 2, to completely close the same.

The smoke pipe or outlet 10 of the heaterA is also provided between the heater and the smoke-flue 11 with a second valve or damper 18, pivotally mounted therein and connected to one end of a link or rod 21, the opposite end of which is connected to the valve 20 at the open end of said smoke pipe or outlet 10 in such a way that when the said valve 20 is manipulated, as will be hereinafter explained, so as to stand in a closed position, as seen in Fig. 2, said valve 18 will be in an open posi-;"

tion, and vice versa, and the valve 18 is provided with an aperture 19 in it to permit the passage through it of smoke at all times, even 'incase the valve be in its closed position.

The valve 20 is connectedto the end of a,

too

chain 23, which may be arranged to extend up to any of the apartments of the building or may be otherwise arranged so as to be conveniently operated, and when said chain 23 is drawn upward it is obvious said valve 20 will be opened more or less and at the same time the valve 18 will be more or less closed, and when said chain is released the valve 20 will fall by gravity and be closed and will act by its connection with the valve 18 to open the same" The valve 20 is connected to the upper end of a second link or rod 25, which extends down through the. vertical pipe 15 and is connected to a valve 24 in the air-boxtl'i, said.

valve 24 being arranged to control therlower endof said pipe 15, when it communicates:

with the box 17, in sucha way that'when the valve 20 is opened the valve 24'will be in a closed position and when the valve 20 is closed the valve 24 will be open. 1

In operation, when it is desired to kindle a fire, or when it is desired that the-:fire in the heater shall burn vigorously, the chain '23 is released, so that the valve 20 falls by its weight, and by its connections with valves 18 andQet acts to open said valves, so th-ata free supply of air from the air-flue 13 (said air beingldrawn fromtheapartments to be ventilated byiway of branch pipes 14:) is given to the heaterb y way of pipes 15 and 16, and a free outlet is provided for the products of combustion by way of smoke pipe or outletlO to the smoke.- flue 11. When the tire is desired .to be re.- duced, the chain 23 is drawn up, so as tomore or less open the valve 20 and more or less close the valves 18 and 24:, so that the supply of'air to the fire-pot of the heaterwill be more or less out 01?, and the outlet to the chimney will also be more or less cut off bythe closing of the respective valves 2i and 18, and at the same time it will be seen that thevalve 20, being opened, allows the excess of airi'supplied to pipe 13 from the branch pipes 14: over what is supplied to theheater to pass through the open outer end of the smoke-pipe 10 to th smoke-fine 11, and so to the chimney. 1

By this construction it is evident that the vitiated air is drawn from the various apartments in a substantially uniform manner, and either fedto theheater or discharged by way of the chimney at all times, no matter whether the firein the heater be low or otherwise; 1 i

From the above description of myimprovements it will be evidentthat the invention is susceptible of considerable modificatio-n'without material departure from its principles andspirit, and for this reason I do not wish-to be understood as limiting myself to the precise construction and arrangement herein set forth. 1 For example, in some cases the pipe 16 may, instead of being connected with the fire-pot of the chimney, be incommunication with one of the air-fines of the heater, so that the air is caused to circulate from the room through pipes 13, 14, 15, and 16 to the heaterflue and back to the room. This arrangement is shown in the fragmentary sectional view, Fig. 4, wherein the pipe 16 is shown as com.- municating with the hot air space orflue 16 of the heater. 7

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A device of the character described, comprising a smoke flue, a heater provided with asmoke outlet having connection with said smoke flue, a valve controlling the smoke out let of the heater, an air flue adapted to draw air from apartments to be ventilated, also having connection with said "smoke flue, a-

valvecontrolling the connection between said air pipeand the smoke line, and means for simultaneously actuating said valves to move one valve into closed and the other into an openposition, substantially as set forth.

2. A device of the character described, comprising asmoke flue, a heaterprovided with a smoke outlet having connection with said smoke due, a valve controlling the smoke outlet of the heater, an air fi-ue adapted to draw air from apartments to be ventilated, having connection with said heater and also having connection with the smoke fiue, valves controlling the connections between the air due and heater and between the air flue and smoke flue, and meansfor simultaneously actuating said valves to move the valve controlling the connection between the air flue and the smoke flue into one position and to move the valves controllin g the smoke outlet of the heater and the connection between the air flue and the heater into the other position, substantially assetforth. t t t 3. A device of the character described, comprising a smoke flue, a heater provided with a smoke outlet having connection with said smoke flue, a valvecontrolling the smoke outlet of the heater, an air flue adapted to draw air from an apartment to beventilated, also having connectionwi-th said smoke due, a valve controlling the connection between the air flue and the smoke fine, a link connection between said valves whereby when one is opened the other is closed, and means for actuating one ofthesaid valves, substantially as set forth.
